Ease way to add JsonObjCodec for types with string transformations about fleece HOT 2 OPEN

I answered you in Stack Overflow, basically your JsonObjCodec does conversions to string but not parsing. I suggested some alternative solutions.

But since you opened an issue here I would like to take the opportunity to evaluate adding some facilities in the library to work with types that don't have json transformations but do have transformation to/from string.

It's an interesting scenario for complex things like composing codecs, and take precisely advantage of codec composability properties.

Thanks for your prompt response! I have also replied on StackOverflow. I would be curious to see what solution you come up with if any.
